+<code bash>

+  * To make a backup of the DB you can issue:
+<code bash>
+mysqldump -h radiusdesk-mariadb -u rd -p --events rd > /tmp/rd.sql
+</code>
+  * There are also a vi editor and the ping command installed for basic editing and network troubleshooting.

+  * You can shell into the radiusdesk-mariadb container with the following command:
+<code bash>
+docker exec -it radiusdesk-mariadb bash
+</code>
+==== Log output ====
+  * Again if you like the fact that you can check log files to confirm everything works well then Docker containers got you covered.
+  * You can run the following command to check the log output of the radiusdesk container:
+<code bash>
+docker logs radiusdesk --tail 20 -f
+</code>
+  * For the log output of radiusdesk-mariadb:
